June 2022 Hydrological Outlook

Period: From June 2022      Issued on 10.06.2022 using data to the end of May 2022

The outlook for June and for June–August is that below normal river flows are likely in south Wales and southern and central England, and normal to below normal flows elsewhere.  Groundwater levels in June and over the three-month timeframe are likely to be normal to below normal across most of the UK.

Rainfall:

Rainfall in May was below average across Wales and East Anglia, although elsewhere in England conditions were more variable owing to localised rainfall.  Northern Ireland recorded above average rainfall and north-west Scotland was exceptionally wet.

The rainfall outlook (issued by the Met Office on 30.05.2022) for June and for the June–August period suggests that there is an increased likelihood of near-average rainfall rather than wet or dry weather.

River flows:

River flows in May were generally below normal or lower across England and Wales, notably so in south-west England and south Wales.  New monthly flow minima for May were established on some rivers in south Wales and the Midlands.

River flows in June are likely to be below normal across much of south Wales and southern and central England, with high confidence in outlooks for continued low flows for some catchments in south-east England.  Elsewhere, normal to below normal flows are most likely.  The same scenario is likely over the three-month timeframe, with below normal flows particularly likely in some catchments in south-east England.

Groundwater:

Groundwater levels in May were normal to below normal across most of the UK.  Levels in south Wales and in some boreholes in southern England and southern and eastern Scotland were notably low.

Levels in June are likely to be normal to below normal in most boreholes.  Notably low groundwater levels are particularly likely for some boreholes in southern England and south Wales.  The three-month outlook is similar to the one-month outlook, though with below normal levels tending more towards the normal range in some boreholes in southern England.
